摘要
根据混凝土"设计强度"和"配置强度"的对比分析,通过目前施工中多种控制预应力张拉时间的措施分析,提出了以混凝土配制强度控制预应力桥梁张拉时间的可行性和重要性。
According to the comparative analysis on design strength and configuration strength of concrete,the feasibility and significance of that the tensioning time of prestress bridge girder is controlled by concrete configuration strength are proposed through analysis on the measures to control prestress tensioning time during current construction.
